The first of these openings is from a book by a professional
and it starts with a statement of general principles which any
player would do well to remember.
Make full use of your own influence. Plan your play to avoid
clumsy redundant formations. Separate enemy stones whenever
possible. Play lightly in areas where the enemy is strong. If
you cannot make a safe group in such areas, run out quickly.
When a few stones are so threatened that rescue attempts would
build up your opponent's strength out of all proportion to the
value of the threatened stones, sacrifice them promptly for advantage
elsewhere.

C[White 8: This is a typical white play in a large handicap game,
and attempts to intimidate Black into believing that his stone
is being surrounded and needs to make eyes on the side.
];B[oh]
C[Black 9: It is important ro separate the white stones. Black
runs out with his attacked /\\ stone by counter-attacking the
weaker white flank.

C[White 10: The usual white response, preserving white 2.

C[White 14: Threatening a further intrusion into the upper side,
and defending himself.
];B[ld];W[kg];B[nn]
C[Black 17: A good move, again attacking white and keeping him
on the defensive.
];W[nm];B[mm]
C[Black 19: Following the proverb "Answer a checking stone by hitting
it on the head".

C[Black 21: Note that Black must play here before protecting at
23(B). If he plays 23(B) now, White answers at A.

C[White 24: Indirectly protecting the cutting point at A and securing
room for eyes.

C[Black 29: After this shutting-in move, white is forced to make
eyes on the side.

C[Black 35: Black could have tried to kill the white group with
B, but then white could take counter measures with the variation
and the situation becomes rather complicated, just what White
wants!

C[White 40: White is now secure with 4 points of territory in his
group, and black can turn his attention to the upper side and
secure the corner. This forces white to run into the centre with
his weak stones and build up the black territory while getting
little himself.

C[Black 51: Should white now play 52' at F, black would reply with
53' at G probably followed by white 54' at H. Black can undertake
such harassing action because his own stones are safe. In this
particular situation, White's stones may live but black is bound
to secure large territories as a result of these manoeuvers.
